开发改进的铜纳米颗粒合成方法对于材料科学技术的进步具有重要意义。在此，淀粉保护的零价铜（Cu）纳米粒子已成功地通过一种新的简易路线合成。该方法基于在低温（80 ° C）下使用抗坏血酸作为还原剂在含水铜盐中的化学还原。采用X射线衍射、扫描电子显微镜和X射线能谱等测试手段对合成的Cu纳米晶的尺寸、结构和组成进行了研究。根据Scherrer公式计算的Cu纳米晶的平均晶粒尺寸约为28.73 nm。预计这项研究的结果使我们更接近设计合理的策略，在没有惰性气体保护的情况下合成新生Cu纳米颗粒。
Development of improved methods for the synthesis of copper nanoparticles is of high priority for the advancement of material science and technology. Herein, starch-protected zero-valent copper (Cu) nanoparticles have been successfully synthesized by a novel facile route. The method is based on the chemical reduction in aqueous copper salt using ascorbic acid as reducing agent at low temperature (80 degrees C). X-ray diffraction, scanning electron microscopy and energy-dispersive X-ray spectroscopy measurements were taken to investigate the size, structure and composition of synthesized Cu nanocrystals, respectively. Average crystallite size of Cu nanocrystals calculated from the major diffraction peaks using the Scherrer formula is about 28.73 nm. It is expected that the outcomes of the study take us a step closer toward designing rational strategies for the synthesis of nascent Cu nanoparticles without inert gas protection.
